EXCAVATO R.

SPECIFICATION forming part of Letters Patent No. 534,241 dated February12,1895.

Application led May 10, 1894. Serial No. 5101758- (NO mod-61|) To allwhom it may concern: Beit known that I, ALEXANDER BARHITE, citizen ofthe United States, residing at Toronto, in the Province of Ontario,Canada, have invented new and useful Improvements in Excavators, ofwhich the following isa specication.

My invention relates to certain new and useful improvements inexcavators, and more particularly to that class that are designed to Ibeemployed in making ditches, the object of the invention being to producea machine of the character designated, which shall combine simplicityand cheapness of construction with durability and efficiency in use.

To these ends my invention consists in the novel construction,arrangement and combination of parts hereinafter fully described anddefinitely pointed out in the claims following the description, duereference being had to the accompanying drawings forming a part of thisspeciiication, whereini Figure l is a vertical longitudinal section ofmyimproved machine taken on the line 1, 1 of Fig. 2. Fig. 2 is a topplan view thereof. Fig. 3 isa transverse section taken onthe line 3, 3,of Fig. 1. Fig. 4 is alongitudinal section of one of the scoops; Fig. 5a plan View of the conveyer supporting frame; Fig. 6, a similar view ofthe conveyer frame; and Fig. 7 a perspective view of a cutter adapted tobe used in conjunction with the excavator.

The main frame A of the machine consists of two side bars a, o., andtransverse beams o, b', b2, b5, the rear end of said frame beingsuspended from an axle c mounted on wheels C,

and the forward end being supported upon by a cross brace B3.

the front axle c by means of arched bar a. To the frame A, and aboutmidway its length, is secured an auxiliary frame B consisting ofuprights B', B2, connected at their upper ends To the inner side of theuprights B', B2, are secured arc-shaped guide ways D provided withdovetailed grooves d within which are tted and free to slide arcshapedjournal blocks d'. Saidjournal blocks are suspended by chains d2 thatwind about pulleys d3 mounted on a shaft d4 journaled in the upperportions of the uprights B', B2, and provided with a crank d5, by whichmeans the `journal blocks may be raised and lowered, for the purposehereinafter described, a set screw d tapped through each of said guideways being employed to lock the journal blocks in their adjustedpositions. v.Iournaled in the journal blocks d is a shaft E carryingradial arms F between the ends of which are rigidly secured scoops G,each of said scoops consisting of a metallic receptacle provided withsolid or closed side walls and a similar outer wallg,the latter beingconvex or arcshaped, and a hinged inner wall g', the free end of whichprojects beyond the end ofthe scoop for the purpose hereinaftermadeapparent. The front end of the scoop is open and its side edges madeoutwardly Haring and gradually tapering from the top to the bottom, asmore clearly shown at g2, Figs. 3 and 4, and the rear end of said scoopis slotted, as at g3, (see Figs. 3 and 4) to. permit the escape of waterand the like when operating upon marshy ground or in clearing outexisting ditches.

Secured to the shaft E in rear of the arms F are arms H which normallyrest upon the rear ends of the hinged lids g and serve to maintain thesame closed. The rear edge of each of said lids is recessed, as at g4 topermit the lid to drop over the end of the arm H, when the latter isdeflected to one side for the purpose, to discharge the contents of thescoop, and to this end the arms H are made resilient and are providedWith laterally projecting lugs h, slightly beveled upon their edges andwhich are adapted vto abut against a beveled cam I secured to theupright B2 which forces the arms H to one side as they come oppositesaid cam and causes them to register with the recesses g4 in the hingedlids g' upon which the latter drop by gravity and discharge the contentsof the scoops. Each of the arms H is provided with a stop or projectionh' which arrests the downward movement of the hinged lid. Upon the rearside of the upright B*a is also secured a cam J which, as the scoops Gpass over it, abuts against beveled lugs g5 which project laterally fromone side of the hinged lids g' and raise or close the latter, and at themoment the lids close the recesses g4 are disengaged from the ends ofthe arms H and the latter spring back into their normal position againstthe lids and hold them in their closed position.

For the purpose of communicating rotary motion to the scoops I providethe following mechanism: To the shaftE is rigidly secured a crown wheelK with which gears a pinion Zsecured upon one end of a shaft L journaledin a bearin g Z secured to one of the journal blocks d', the other endof said shaft being journaled in a socket bearing Z2 provided with asleeve Z3 loosely embracing the axle c. Upon the shaft L is mounted by aspline and feather a pinion Z4 that gears with a crown wheel M keyed tothe axle c, the said pinion being capable of being moved longitudinallyupon the shaft L to throw the mechanism in and out of gear, and for thispurpose is engaged in the usual manner by a hand leverN provided with aspring pawl n that is adapted to engage one of the notches of asegmentn.

0 indicates a curved shovel plow that is carried by an arm o journaledon the axle c, said plow being provided upon its opposite edges withprojections o to which are secured chains o2 that are wound 'about thepulleys cl3 that are employed for raising and lowering the scoops G.Said plow follows immediately in the path of the scoops and in closeproximity thereto, and serves to take u p any earth left by the plows.By winding the chains o2 about the pulleys d3 the plow and scoops areadj usted simultaneously and equally, the two thus always maintainingthe same relative position toward each other.

To the forward portion of the frame A, and to one side thereof, issecured a conveyer support P. Said support consists of a rectangularframe provided at one end with two hinge butts p and with a brace rod 10secured at one end to the outer end of the frame P and atA its other endprovided with an eye p2 said support being pivotally secured to the sideof the frameA by means of a rod p3 which passes through the hinge buttsp and eye p2 and through eye-bolts p4 secured to the side of the frame,said rod p3 being headed at one end and at its other end provided with anut for detachably securing it in place. To the under, outer side of theconveyer support P is secured a caster wheel p6 that prevents thesupport from sagging under the weight of the conveyer. Resting betweenthe beams b2, b3, of the frame A and supported by shoulders b5, b, andthe support P is a transverse endless conveyer Q. Said conveyer consistsof an elongated rectangular frame R (see Fig. G) the side bars fr ofwhich are provided upon their under sides at equi-distances apart withapertures fr', and in the opposite ends of said frame are journaledshafts r2 carrying sprocket wheels r3 about which the endless conveyerpasses. The endless conveyer consists of an apron S, of canvas or anysimilar or suitable material, having secured to its outer surface aseries of transverse strips or battons s, while the inner surface of theapron, and near its opposite edges are se` cured drive chains s whichengage and travel about the sprocket wheels r3.

For conveying motion to the conveyer I employ the following mechanism:To one of the rear wheels C, I secure a crown wheel T with which meshesa pinion u mounted and longitudinally adjustable on a shaft U secured insuitable bearings on the sid-e beam a. of the frame A, said shaft at itsforward end projecting through an elongated slot r4 formed in one of theside bars of the conveyer frame R and at its extreme end provided with asprocket wheel fu. that engages one of the chains s and by which theendless conveyer is driven. The sprocket wheel a is provided with a handlever and segment similar in all respects to that employed in connectionwith the pinion Z4 on the shaft L before described. The conveyer supportP is, provided with a series of tenons p5 that are adapted to fit withinthe apertures r in the under side of the conveyer frame R. By slightlylifting up the conveyer frame so as to disengage the tenons from theapertures the said frame and the conveyer may be moved in and outrelative to the frame A so as to deposit the earth at any suitabledistance from the machine. To the upper edge of the beam b2 is hinged achute V provided upon its under side with a stop QJ that serves to limitthe downward or rearward movement of the chute, said chute serving toreceive the earth as it is discharged from the scoops and direct it ontothe conveyer.

In digging ditches or trenches it is always desirable to first run aplow along the proposed route to be followed, to loosen up the earth,and in Fig. 7 I have shown one form of plow that serves admirably forthe purpose. As therein shown said plow consists of two substantiallyvertical cutters l, l, united at their bottoms by a horizontal cutter 2,tliesaid plow being designed to be run ahead of the excavating machineto cut and loosen the earth.

From the foregoing description the operation of my improved machine willbe readily understood. The journal blocks being ad justed to the properheight to give to the scoops the depth of penetration desired, the plowO being lowered into position, and the conveyer moved out to one side ofthe frame to deposit the earth at the desired distance the machine isdriven over the route first traversed by the plow illustrated in Fig. 7,or such other form of plow as may have been used for the purpose. Therear axle and wheel C actuate the shaft E and the conveyer, as beforedescribed, and as the shaft E revolves the scoops G are successivelycaused to dip into the loosened earth with a downward and then an upwardsweeping motion which tllls the scoops. As they continue to revolve thescoops successively strike and raise the chuteVto permit their passagepast the latter, the chute falling back into position as each scooppasses it. After each scoop passes the chute V and reaches the positionshown in Fig. 1 the lug h on the arm H will abut against the cam I andforce said arm to one side to permit the hinged lid g to drop,

Ioo`

thus discharging the contents of the scoop onto the chute V whichconveys it onto the endless carrier S, the latter carrying it to oneside of the machine and depositing it. As each scoop in turn passes overthe cam J, after having discharged its contents, the beveled lug g5 onthe hinged lid g abuts against said cam which raises and closes said lidand at the same time causes the lid to disengage the end of the arm Hwhich, owing to its resiliency, is immediately deflected slightly to oneside and bearing against the surface of the lid holds the same in itsclosed position, and puts the scoop in condition for taking up its nextload. As lbefore described the shovel plow O follows immediately in thepath of and in close proximity to the scoops and serves to take up anyearth left by the scoops, and the latter in their revolution and beforethey enter the earth, scoop out and take up from the plow the earth itaccumulates.

To prepare the machine for transportation the mechanism for actuatingthe scoops and the conveyer is thrown outof gear in the manner beforedescribed, the scoops elevated to clear the ground by winding up thechains d, and the plow O is swung up about its hinge and supported inany suitable manner. If desired the conveyer support P may be instantlydetached from the machine by unshipping the bolt rod p3 and placed upontop of the conveyer or other suitable portion of the machine, when theentire machine may be readily conveyed from place to place withouttaking up more room than an ordinary vehicle.

In the drawings I have for the sake of clearness shown only two scoops,but it will be readily understood that any suitable number of scoops maybe secured to the axle D, the number depending in a great measure uponthe size of the machine and the scoops.

I wish it to be understood that I do not confine myself to anyparticular construction of plow, as any form found preferable or desiredmay be employed without departing from the spirit of my invention.
